Abstract

The invention discloses a production method of a surface passivator and coating used for a zinc-aluminum-magnesium plating product. The production method comprises the procedures of passivator preparation, finishing, coating and drying, and the passivator is composed of high-crosslinking resin, silane, nano silicon oxide, a corrosion inhibitor, an antioxidant and water. By controlling the roughness of a finishing roller, the finishing process, the coating process, the drying temperature and the like, a zinc-aluminum-magnesium product passivated steel plate which is excellent in blackening resistance and integrates multiple excellent functions such as environmental protection, fingerprint resistance, corrosion resistance, heat yellowing resistance, solvent resistance, flame retardance and coating performance is obtained, the requirements of European Union Rohs environmental protection instructions are met, and the thickness of a passivation film layer of the obtained zinc-aluminum-magnesium plating layer passivation steel plate is 1.0-1.5 g / m < 2 >.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a surface passivating agent for zinc-aluminum-magnesium coating products and a coating production method. Background technique [0002] In order to further improve the corrosion resistance of steel materials, zinc-aluminum-magnesium (Zn-Al-Mg) coated steel sheets have been widely developed and put into use. Zn-Al-Mg coatings are based on the composition of pure zinc coatings, adding magnesium, aluminum Such elements are often obtained by hot-dip plating in industry. The main application fields include 5G base station construction, photovoltaic industry, home appliance industry, animal husbandry industry and automobile industry, etc. At present, home appliances such as air conditioners produced by zinc-aluminum-magnesium (Zn-Al-Mg) coated steel sheets have appeared on the market, which have excellent corrosion resistance and cut protection. [0003] The zinc-alumi...
